LABELING-MACHINE.

Specification of Letters Patent.

Patented Nov. 28, 1905.

T0 all whoml it may concern:

Be it known that I, J OHN B. AUFULDISH, a

citizen of the United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements inLabeling-Machines, of which the following is aspecification. This machine relates generally to improvements inlabeling-machines of the kind employed in labeling cans, bottles, orarticles of like nature,and specifically to improved means foroperatively controlling the mechanism employed in drawing the label overthe pasteroller and placing it in position to be applied to the can.

The object of the invention is to construct a label-gripping machinewhich Will be positive in its operation, simplified over the presentforms employed, and more economical in construction and operation.

The type of machine to which this improvement is applicable isillustrated in United States Letters Patent to Neth and Aufuldish, No.585,282, granted June 29, 1897. These machines have rotary can-carryingarms, preferably in duplicate, which convey the cans from thefeeding-chute t0 the labeling devices and thence to the-discharge-chute,and for each revolution of the shaft carrying the canholding arms twocans will have labels applied thereto. In order to accommodate thelabeling of two cans during one revolution of the driving-shaft, thepresent device is so constructed that the label-gripping fingers will bemoved forward twice during each revolution of said shaft, therebyplacing a label on each can when it reaches a position to receive thesame. In this type of machine the labelgripping fingers are movedforward twice during each revolution of the driving-shaft; butheretofore the mechanism for accomplishing the same has been more orless complex, more costly, and not positive and accurate in itsoperation.

difiiculties have been obviated and a mechanism constructed comprising acam-faced cylinder driven by the main shaft at a relative speed of twoto one by suitable connections therewith, so that the label-grippingmechanism is positively driven forward to seize the label twice for eachrevolution of the driving-shaft. v

In the present invention the above-named.

With these ends in view I have devised and constructed thehereinafter-described invena vertical section of a can-labeling machine,

showing the present improvements applied thereto. Fig. 2 is a verticalsection of the improved device for operating the label-grippingmechanism. Fig. 3 is a detail view of the cylindrical cam. Fig. 4 is adeveloped view of 5 the cylindrical cam. Fig. 5 is a plan view of Fig. 2with the cam removed. Fig. 6 is an end elevation looking to the right ofFig. 5. Fig. 7 is a detail view of the cam-roller.

Referring to Fig. 1, the general construc- 7 tion of a can-labelingmachine to which the present improvement is applicable is described asfollows: 1 is the main frame of the machine, so constructed and disposedas to afiord proper support for the various elements of the mechanlsm. 2is a chute or guideway into which the cans to be labeled are placed anddown which they travel. 3 is the main shaft, and 4 4: are can-gripperscarried by and rotating around said shaft and adapted to take the cansfrom the lower end of the chute 2 to carry them to the position to whichthe right-hand gripper 4E is shown, at which point a label is appliedthereto from the pile of labels 5 and then to carry the said can up anddeliver it 5 upon the delivery-chutes 6, whence it is conveyed to anydesirable place. The pile of labels 5 is carried upon a platen or table7, supported upon a vertical sliding rod 8, and

is pressed up by the adjustable weighted le- 9 ver 9. 10 is abuckling-roll for moving the label ofi the pile. l1 and 12 arerubber-covered feed-rolls adapted to receive the label from the pile andconvey it over the pasteroller 13, from which position it is taken bythe label-gripping mechanism and placed upon the can. 14 is a framecarrying the lap-laying and label-laying rollers.

The devices shown at 15 and 16 are employed to release and retain thecans on the feeding-chute, and at 18 a belt is shown which is adapted toroll the can along the deliverychute.

The mechanism for handling the label and placing it in position to beapplied to a can is 1 5 constructed and operated inthe following manner:Freely mounted on the operatingshaft 3 is a block 20. 21 is a bracket orframe, one end of which is fastened to the block 20 in any suitablemanner, such as screws, as shown in Fig. 5. The other end of the saidframe or bracket 21 is supported on and secured to the machine-frame 1.The frame 21 has a longitudinal groove 22, as shown in Figs. 2 and 5, inwhich rides the gripper-bar 23. The gripper-bar 23 slides with a freelongitudinal movement in the groove 22 and is held within said groove bythe cam-shaft-supporting bracket 25 at one end and a plate 26 at theother end. Mounted on the left-hand end of the gripper-bar 23, as shownin Fig. 2, are'the label-gripping fingers 27 and 28. The fingers 28 arespring-controlled and are actuated to open and close upon the label bycams or other suitable mechanism. (Not shown, asit does not form part ofthe present invention.) Journaled in the bracket 25 and theupwardly-projecting portion 21 of the frame 21 is a shaft29, upon whichis rigidly mounted a cylindrical cam 30. The cam-face of the cylindricalcam 30 is engaged by a cam-roller 33, rotatably supported on a stud33,said stud being secured to the gripper-bar 23. The cam-roller 33 isheld against the operating-face of the cam by means of a weight 35, (seeFig. 1,) said weight being attached to one end of the gripper-bar 23 bya cord 38 and guided by a pulley 39, supported in the end of the frame21. The shaft 29 is prevented from longitudinal movement by the collar31, which is pinned to said shaft and abuts the bracket 25 and thecylindrical cam which abuts the portion 21. Forming part of the bracket21 is a dependent journal-bearing 40, in which is journaled a shaft 41,said shaft carrying at one end a spiral gear 42, which is adapted tomesh with and be driven by a spiral gear 43, rigidly mounted on the mainoperating-shaft 3. These spiral gears 42 and 43 bear a two-to-onerelation with each other, so that for each revolution of the maindriving-shaft 3 the shaft 41 will receive two revolutions. Asprocket-wheel 45 is carried on the shaft 41 and drives a sprocket-chain46, which engages and drives a sprocket-wheel 47, rigidly mounted on thecam-shaft 29, thereby imparting motion to the cam-shaft. Thus it will beseen that for each revolution of the main driving-shaft the cylindricalcam 30 will be given two revolutions, thereby projecting the gripper-barand gripper-fingers forward to a position where a label will be seizedand placed upon each can when said can is brought to the proper positionto receive the label by the cancarrying arms. The cylinder 30 has acamface which engages the cam-roller 33, carried by the gripper-bar 23,and moves said gripperbar and gripper-lingers 28, attached thereto,directly forward to a position to seize the label when such label ispassed over the paste-roller. When the cylindrical cam is rotated in thedirection of the arrow shown in Fig. 2, the camroller 33 will ride upthe inclined portion 30. which will be seen by referring to Figs. 3 and4, Fig. 4 being a diagrammatic view of the developed condition of thecam until it reaches the portion 30 which is the limit of throw of thecam. At this point the gripper-bar will have been projected sufiicientlyfar forward to seize the label, whereupon the cam-roller will quicklytravel back over the inclined surface 30 until it reaches the surface30, where the grippers will hold the label momentarily until thelabel-laying mechanism has placed a label on the can, whereupon thecam-roller will travel back over the surface 30 during which movementthe grippers will be open to release the label and the bar resume itsnormal position, as shown in Fig. 2. This operation will be repeatedtwice for each revolution of the main shaft, owing to the fact that thespiral gears 42 and 43 are made with the twoto-one relation with eachother.

The general operation of the machine is as follows: When the main shaftis operated, the label-feeding mechanism will feed a label over thepaste-roller, so that its end will project sufliciently far therefrom toallow it to be seized by the gripper-fingers. Simultaneous with thismovement the gripper-bar 23, carrying the gripper-fingers 27 and 28,will move toward the paste-roller by reason of the camroller 33 beingoperatively controlled by cylindrical cam 30. The gripperfingers willwhen they reach the end of the label seize the same, at which time thecam-roller is at the extreme point 30 of the cylindrical cam. Fur,- therrotation of the cam will cause the gripper-bar and gripper-lingers torecede, carrying with it the label, by which time the cancarryinggrippers will have moved the can to a position to receive the label, asshown in Fig. 1. The cam-roller 33 is traveling over the cam portion 30when the parts are in the position shown in Fig. 1, which momentarilychecks the receding movement of the gripperbar and allows thelabel-laying mechanism to place the label on the can. Continued rotationof cam 30 will cause the gripper-fingers to recede and move down theportion 30 of the cam, during which operation they will be opened, thelabels released, and the gripperoperating mechanism be in the positionshown in Fig. 2, which is the normal position. When the can-grippers4,which are diametrically opposite to the grippers just described, reachthe position shown in Fig. 1, the label-gripping mechanism will havebeen again operated to seize a label and place it in position to beapplied to the can in the manner hereinbefore described.
